To 521 whom it may concern: I

Be it'known that we, CHARLES T. WEST- LAKE and CHARLES F. FREDE,citizens of the United States, residing at St. Louis,"-M1ssouri, haveinvented a certain new and useful Improvement in Bufiing Mechanism forCar- Plat-forms, of which. the following is a full, clear, and exactdescription, such as Wlll enable others. skilled in the art towhich it'appertains to'make and'use the same, reference being-had to theaccompanying drawings, forming part of-this specification, in which- I'1 Figure 1 is a top plan. view of a cast metal platform withportions'fof the,bufier beam "and end sill and showing the buflingmechanism in position thereon. Fig-2 is a longitudinal section takenapproximately on the line 2-2 of Fig. 1 Fig; 3 is an enlarged sectiontaken on theline 33 .of F ig. 1. Fig; l is :alt'ra-nsverse section.taken on the line 4-'4 of Fig.1. f

This, invention relates generally to improveme'nts in railway c'a'rplatform coni 7 ing mechani'smapplied to cast metal plat-- forms, suchas are now in general use 1n passtruction and more particularly to thebuffsenger car construction, and the principal obj ects of the inventionskeleton platform. and buffer beam so that a form of' bufiing mechanismof accepted M. C. B. type and'n'ow'in use on a number ofpassenger' carsmay be readily applied to said platform and buffer beam and, further,

to provide a construction wherein the operating parts of the buflingmechanism can readily be placed in or removed from posi-, tion withoutdetaching the vestibule orbuffer from its stems, therebypermitting thebufling mechanismtobe easily and.

quickly repaired when any of the operating parts have become broken or.unfit for service, I

With the-above objects in View, our invention consists in certain novelfeatures of construction and arrangements of parts hereinafter morefully described and claimed.

Referring in' detail to the accompanying drawings: 1 designates the endsill of a cast metal car under frame of the-type now in general use andformed integral with and projecting forwardly therefrom is a series 7 ofvertically disposed webs 2 and horizonare: to construct a bufi'er beam.

tallydisposed plates 3, which form a skeleton platform, Formed: integralwith the forward end of this-skeleton platform is a buffer beam'4 of the'iisual box shape and positioned on top of the central portion of saidbeam'fis a threshold "plate 5.

The numeral 6 designates a bufling member of the usual form 'whichoccupies a position'immediately in front of the bulfer beam,

and positionediontop this bufling member is a plate? which is adaptedto. slide beneath the plate 5. The buffer 6 is carried upon the forwardends of a pair of side'bufit'er stems 7 and the central portion of saidbuflei' bears against the forward .end of a centerbufiing -stem 8..Allof the buffer stems are arranged to slide freely throughcorresponding openings 9 formed in the front and rear walls of thebuffer beam 4.

The numeral 2 webs which occupy platform," and formed integral with .the

upper edges of these 'websis a horizontally disposed plate 3,Formed'integral with the webs and with the plate 3 is a transverselydisposedwall 10, through which is designates thepair of positions onoppositesides of the transverse center of the skeleton formed anopening-11, which is in .alinement with the center bufie'rstem openingsin the The forward-portion ofthe-center bufier stem 8 is preferablysquare or non-circular in cross-section and the rear portion of the saidstem is preferably round in cross-seci tion, and positioned against theshoulder be-' tween the rounded rear portion'and the square 12. 'A"'rear follower plate 13 is positioned on the-rounded rear portion 'of'thecenter stem and normally bears against the transverse wall '10, andmounted on'the rounded posed between t he plates 12 and 13 is acomparativel'y heavy coil '5 end ofthe jcenter bu er stem 8 operatesthrough the openingll in the transverse wall 10,- and' a pm or key 15 isinserted latform to the '90 forward portion, is a'di'sk or followerplate rear portion of'the centerstem and interringl4, The rear thecollars 1 8 and mounted on said rear ends, are nuts 19. The forwardportions of the side buffer stems 7 are preferably square ornon-circular in cross-section and the rear portions. are round incross-section.

Ada ted to bear against the shoulders forme between the square ornon-circular forward portions and the round rear portions of these sidestems, are disks or follower plates 20, and bearing against said platesare the forward ends of-side bufier stem springs '21-, therear ends ofwhich bear against the forward ends of the 001 his 18.

Under normal conditions, the butter springs 21 and 14 maintain thebuffer 6 at its outward limit .of movement, and when said buffer ismoved inward toward the beam 4, during the coupling of two cars,

said springs will be compressed andwill be therefore simultaneouslythrown into action to yieldingly resist the inward movement of thebufier and buffing mechanism, until said parts have been moved to such adegree as to permit the coupling of the cars.

The buffer stems are mounted to move freely through their bearings andthe springs mounted on said bufi'er stems readily combine. to yieldin lyresist any inward movement of the bu er.

The construction herein described is comparatively ,simple, provides astrong and said construct-ion is especially advantageo'us when it isnecessary to make repairs or to'renew any parts which have become wornor broken inv service.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of our improved bufling mechanism, canbe made and substituted for those herein shown and described withoutdeparting from the spirit ofour invention, the. scope of which is setforth in the appended claim;

'In a bufiing .mechanismof the class described, the combination with acar end sill and buffer beam, of a skeleton platform integral with saidend sill and buffer beam, which platform comprises aseries oflongitudinally disposed members which are T- shape in cross section, aseries of transversely disposed webs arranged between saidlongitudinally disposed "members, and bearings formed in saidtransversely disposed webs for the'rear portions of the center and sidebufler stems.
